eclipse插件开发常用的选择器

容器选择器（IFOlder,IPROJECT ,包等）：

ContainerSelectionDialog dialog = new ContainerSelectionDialog(
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell(),
ResourcesPlugin.getWorkspace().getRoot(), false,
"Select new file container");
if (dialog.open() == ContainerSelectionDialog.OK) {
Object[] result = dialog.getResult();
if (result.length == 1) {
org.eclipse.core.runtime.Path path = (org.eclipse.core.runtime.Path) result[0];
srcPath = path.toString();
System.out.println("=============" + srcPath);
srcPath.endsWith("src");


}
}

类选择器：

SelectionDialog s = JavaUI.createTypeDialog(shell,
null,
project.getProject(),
IJavaElementSearchConstants.CONSIDER_ALL_TYPES,
true);
if (s.open() == org.eclipse.jface.window.Window.OK) {
SourceType type = (SourceType) s
.getResult()[0];


unit = (ICompilationUnit) type.getParent();
LinkedList list = new LinkedList();
getPackage(unit, list);
pac = listToString(list);
text1.setText(pac);
}

系统目录选择：

DirectoryDialog dirDlg = new DirectoryDialog(shell);
String dir = dirDlg.open();

系统文件选择:

FileDialog fd = new FileDialog(
final String fileStr = fd.open();
